I bought the 16GB version and thought USB3 is faster than USB2. This assumption is unfortunately only valid for the read operation - writing lasts exactly as long as with USB2 :-( Rough thumb rule is keeping: at least 1min / 1GB. My USB2 sticks do it also. My ext. USB2 HD is faster. The reading is then about 4 times faster. ... And why the stick does not even have a tiny LED for function control, I do not understand. The Flash technology is probably the cheapest variety - the housing is OK.
Conclusion: Dear drauflegen a few euros and buy a faster drive (with indicator LED)!
